When doing long calculations P keeps appearing and then I have to start over. How do I make it stop? What does it mean? I no longer have a manual for this adding machine.

Re: P keeps appearing

Have same problem with the randomly appearing"P" and no end frustration with it. Tried loosening, (...the screws very extreemly tight), tried with no success, then tightened again, but still no success. Thanks, though, for the suggestion!

Re: P keeps appearing

Have the same problem! Put it on our deck during the

full moon, but that didn't help any more than loosening and tightening the screws! Have to find a new one, I guess.

Hi stephanie.

Try unplugging it, then plugging back in. That should reset it.

Sometimes these machines seem to think we're trying to do what they are not capable of so they go into information overload.

If you got a manual with the unit there may be a full explanation.

Usually E just means "error" and the machine cannot do what it thinks you have requested.

Cheers.

What does that mean adding? Displaying extra zeros? If that is the case Press [2nd][.] and limit the number of decimal you want.

You can put the calculator in FLOating mode: Press 2nd DRG and choose FLO.

It sounds like you need a manual for your calculator. You can download a scanned copy here, and it will explain what all the keys are for. For now, here is the way to set the calculator for a five decimal place display:

Spend some time reading the manual and work with the calculator. It's a powerful tool with a lot of capabilities. Thanks for using Fixya!

- Press the MODE key three times. A menu offering choices of FIX, SCI or NORM will appear.
- Press the 1 key to select FIX mode. The message "0~9?" will appear.
- Press the 5 key. This tells the calculator to display five digits after the decimal.

- Calculator must be in SD mode (standard deviation mode) :Press [MODE] [.]
- However, if [FIX] or [SCI] appears on display you must press [MODE][9] first.
- Data input always starts with [SHIFT][SAC], to clear the registers of old data.
- Type a number and press the [DATA] key, it is the [M+] key at the bottom right of keypad.

Press [SHIFT] [9] (sigma n-1) to get sample standard deviation

Press [SHIFT][8] (sigma n] for the population standard deviation

Press [SHIFT] [7] (xbar) for the mean

Press [SHIFT] [6] (n) for the number of data entries

Press [SHIFT] [5] (capital sigma x) for the sum of values

Press [SHIFT] [4] (capital sigma x to y) for the sum of squares of the values

For additional information you might consider taking a look at the calculator manual.

Hello,

The most likely reason is that the backup battery is drained. Change the backup battery. When you get the Ram Cleared message, just press [CLEAR] to erase the message and start using the calculator.

Hope it helps.

Enter the first number, 1.

Hit the σ+ (Sigma+) key. ( n=1 will appear in the window)

Enter the second number, 1.

Hit the σ+ (Sigma+) key. (n=2 will appear in the window)

. . . . .

Enter the last number, 7.

Hit the σ+ (Sigma+) key. (n=7 will appear in the window)

Hit 2nd x2 (by hitting the 2nd key you are actually selecting the x-bar written above the key.) This gives you the mean.

Hit 2nd sqrt(x). This gives you the sample standard deviation which we will use in class.

Make sure you turn your calculator off and on for new data sets.

This calc will do standard deviations. In the manual it is on page 2 and also on page 40.
